S PECIFIGATION forming part of Letters Patent No. 646,015, dated March2'7, 1900. Application filed December 23, 1897. Serial No. 663,146. (Nomodel.)

To all whom it may concern: Be it known that we, HENRY PEROY BOUL- NoIsand JOHN ALEXANDER BRODIE, subjects of the Queen of Great Britain andIreland, re siding at Liverpool,in the county of Lancaster, England,have invented Improvements in and Relating to Refuse-Destructors, ofwhich the following is a specification, and which was patented in GreatBritain November 16, 1891, No.19,803. This invention relates toapparatus commonly known as refuse-destructors used for burning townrefuse and the like; and the object of the invention is to reduce thelabor of working such apparatus by modifying the construction thereofand providing appliances for use in connection therewith,-

whereby handling of the refuse is as far as possible eliminated.

Refuse-destruotors consist, usually, of a stack of furnaces or cellslying side by side and communicating at their back ends with a commonfine. In some cases a double arrangement is adopted, the stackconsistingof pairs of furnaces lying back to back on each side of the common fine.The front portion of each furnace is floored with fire-bars, theremaining portion, extending from the ends of the fire-bars to theopening to the common flue, acting as a drying-hearth. The refuse is fedonto the drying-hearth of each furnace from a charging-platform on thetop of the stack through a charging hole and is pushed or pulled forwardonto the fire as required, the fire being worked from the lower orground level through a fire-door at the front of the furnace. The refuseis tipped onto the charging-platform from a dump or cart platform at ahigher level, and as the bulk ofthe refuse arrives during acomparatively-short part of the day it accumulates, and according toexisting arrangements considerable handling is thereby necessitated inorder to feed it through the charging-holes. As already stated, theobject of our invention is to eliminate as far as possible handling ofthe material treated in the destructors.

Figure l of the accompanying drawings shows, partly in elevation andpartly in Vertical section, the general arrangement of apparatusaccording to this invention. Fig; 2 is'a plan, and Fig. 3 an endelevation, of the truck. Figs. 4 and 5 are sections on the lines A A andB B, respectively, of Fig. 6; and Fig. 6 is a plan showing enlargedviews of details of the. charging-door and truck-doors and mechanism foroperating them. Figs. 7, 8, and 9 are similar views to Figs. 4, 5, and6, respectively, showing a modification of the details illustrated inthe latter figures. Fig. 10 is a similar view to Fig. 7, but showingcertain parts in different positions.

Throughout the drawings similar parts are indicated by the samereference-figures, and in the case of sections the direction in whichthey are viewed is indicated by the small arrows placed adjacent to theletters denoting the plane of section.

1 is the charging-hole of the f urnace, which is placed over thedrying-hearth 2 and has a width equal to that of the hearth orapproximately so in order that refuse can fall directly onto the hearth.The flue-opening 3 is .also preferably made equal or approximately equalin width to the hearth. The door 4: of the charging-hole beingcomparatively large and exposed to a considerable temperature, it isformed preferably of iron, arched and covered below with fire-brick orother refractory covering. The door 4 is opened and closed, preferably,by traversing it laterally, the seating 5, Fig. 5, against which theprojecting ledge 6 on the door closes, being inclined to the rails 7,upon which the wheels 14, supporting the door, traverse, so that whenthe door is closed the ledge 6 comes into close contact with the saidseating 5. The seating may be above or below the corresponding ledge onthe door, although the former is generally preferable, as by thisarrangement, which is the one shown in the drawings, the refuse cannotlodge on the seating. r

The following arrangements are provided for storing the refuse anddelivering it into the charging-holes without the necessity of handlingit. For each furnace (or pair of furnaces, if so arranged) there is orare provided one or more trucks 8, consisting or each consisting of anumber of adjacent compartments or bins placed in line, the width of thetruck being about equal to that of the charging-hole. The side walls ofthe truck are ex tended up considerably higher than the transversedivision-boards of the adjacent compartments or bins. This permits ofthe d umping of large cart-loads of refuse directly into I the truck,the high sides thereof causing it to run into the various compartmentsand preventing the material being spilled over. Each truck is carried bywheels 25, running on rails 9, carried on the charging-platform andextended beyond it at each side a sufficient distance to allow all thebins to be brought in succession vertically over the charging-hole oreither hole of a pair, as the case may be. The dump or cart platform 10is placed over the rails sufliciently high to allow the trucks to be rununderneath it, and when the carts are tipped the truck is worked alongthe rails as each bin is filled by means of the handle 22, pinion 23,and spur-wheel 24.

For discharging the bins into the chargingholes the bottoms of the binsare so made that they can be individually opened and closed by suitablegear. The bottoms are preferably made in the form of doors 11, hingedand arranged to open and close automatically when desired by supportingtheir free ends on rollers 12, arranged to run on rails 9,carried by thecharging-platform, portions 13 of the said rails being movable at will,so that when a bin arrives at the proper position over a chargingholethe bottom may be allowed to open by lowering or laterally displacingthe portions 13 of the rails upon which it is supported for the timebeing. If the said movable portions of the rails be supported by thedoor of the charging-hole, it will be seen that the discharge of thebins becomes automatic as a result of opening the chal'gingdoor.

The charging-hole door, as before mentioned, is carried by wheels 14,running on rails 7, and it is closed or opened by means of the lever 15,working in a recess or guide 18, formed in the top of the furnace. Thislever is fulcrumed at 16 and connected to the door 4 by theconnecting-rod 17. The details of the door4and the arrangement wherebythe opening of the door allows the bottom of the bin over thecharging-hole to open are shown in Figs. 4 to 10.

Figs. 4, 5, and 6 show an arrangement whereby the bottom of each bin isformed by two doors 11 and in which there are two movable parts 13 toeach main rail 9, which drop down when the door 4 opens.

Figs. 7 to 10, inclusive, show an arrangement in which the bottom of thebin is formed by one door and in which the movable part of the rail iscarried by the door 4 and is displaced laterally when the latter isopened.

The rollers 12 of the doors 11 are supported by the movable portions 13of the rails 9, these movable portions being fulcrumed at 19 andconnected together by a connecting-rod 20. The movable portions aresupported by the bearing-rollers 21, carried by the framework of thedoor 4. It will be seen that when the door 4 is opened the portions 13and the doors 11 drop into a vertical position, as shown in Fig. 1, andallow the refuse from the bin to fall through the charging hole 1 ontothe hearth 2. When the door 4 is closed, the first bearing-roller 21raises the near movable rail, and the other rail is raised by theconnectingrod 20, and when the door 4 is fully closed thebearing-rollers support the movable rails, which in turn support thedoors 11.

Figs. 7, 8, and 9 are analogous views to Figs. 4, 5, and 6 andillustratea modification of the details shown in the latter views. Thebottom of each bin in the modified arrangement is formed by a singledoor 11, which construction admits of there being but one movable part13 of the rail 9, which supports the rollers 12 and which is nowseparate from the main rails, which may be made continuous. The movablepart 13 is carried by the door 4 and when endwisely displaced by thedoor being opened allows the door 11 to drop into a vertical position,as shown in Fig. 10, and so leaves the refuse free to drop through thecharging-hole 1 onto the dryinghearth.

The capacity of the trucks should be suflicient to store the greatestaccumulation of refuse that is likely to occur during the ordinaryworking of the destructor, and the capacity of each bin is preferablyjust sufficient to fully charge the furnace when dis charged into thelatter.
